As an open package, OpenFOAM gives users the opportunity to customize the already extensive range of functionalities and create even more relevant and ground-breaking applications.

Incompressible Turbulent Flows

Many products and components begin as molten fluids. Computational fluid dynamic software packages allow engineers to model the behavior of these fluids as they are poured and cast.

This allows the engineers to try out different designs, arrive at the most precise one and end up with a product that will perform exactly the way they anticipated. This in turn means that companies can use these techniques to rapidly create new products, thereby reducing the cost of bringing new designs to market. This is obviously a tremendous benefit when striving to be a more profitable and successful organization.

Application using multiphase include particle deposition, effect of waves on ships, effect of gasoline tank shaking. Discontinuous and overset mesh allow for various methods to simulate moving objects. Discontinuous mesh makes it possible to analyze a combination of rotation and translation such as a piston pump, or shear forces during application of a disk brake. Overset mesh incorporates a stationary and moving mesh.

Applications with deformation, rotation, or multiple moving regions can be simulated using this approach. Examples using overset mesh include, a gear pump or opening and closing of an engine port valve. A density-based solver keeps the calculation stable during high Mach number simulations. Depending on the objective, either solver can be specified for the analysis. CFD is capable of considering all three modes of heat transfer.

In addition to natural and forced convection, radiation can be solved using either the flux or view factor method. With view factor reflection, transmission, and refraction can be considered.

  5. In boiling can be predicted for a fluid by considering the nucleate boiling coefficient. Sound caused by pressure oscillation of fluid, such as wind noise, and sound caused by resonance can be predicted using Large Eddy Simulation LES and a weak compressible flow model.

    Theoretical and Computational Fluid Dynamics

    A Fast Fourier Transform calculation can be used within the software to predict the frequency of noise. Using previous simulation results, Optimus for Cradle can be used to search for an optimal design. Multiple design variables and multiple design objectives can be considered using a genetic algorithm. Computational Fluid Dynamics. Utilizing CFD software has become an indispensable tool in reducing development costs by enabling users to quickly handle more realistic geometries and physics.
